[Mod] Find Biome [1.2.0] [findbiome]

[Wuzzy]

Find biomes with a single command.

This is a mod for game developers. This will help you find biomes quickly. It adds two server commands:

• findbiome <biome>: Find a biome and teleport to it
• listbiomes: List all biomes

This is very helpful when you're tweaking biomes of your game and don't want to search all over the world. The biome finding functionality is also available to developers (see the readme file).

Note: To find biomes in v6 mapgen, you need to use the Biome Info API mod.

Limitations
It's rare, but the mod might not find your biome if it is very obcure, but even then it should be unlikely. If this happens, just move somewhere else and try again.

Mod infos:

• Current version: 1.2.0
• Works in Minetest 5.0.0
• Optional dependency: biomeinfo (adds support for v6 mapgen)
• Download: https://codeberg.org/Wuzzy/minetest_fin ... /1.2.0.zip
• Git project page: https://codeberg.org/Wuzzy/minetest_findbiome
• License of everything: MIT License

That's great! Thanks!

Cool for modders to test things. Or for a mod to teleport to biomes too.

[TumeniNodes]

Nice Wuzzy... thank you

[CalebJ]

Awesome, Wuzzy! Thank you, I've been wanting something like this for a long time :)

[StarNinjas]

I.. I Like P-P- Potatoe? Thanks SO MUCH Wuzzy I have always dreamed of this!!!
Thanks Again

Sounds like a very useful mod. If you start a new world and are searching for a particular biome, that biome certainly wouldn't be the one you started in :-) So - thanks for the mod!

[Wuzzy]

Version 0.2.0 released!

Now with mapgen v6 support! But you need to use the biomeinfo mod for it to work.
For the other mapgens you don't need any other mod.

This is currently broken, attempt to use /findbiome in a biome-mapgen.

Code: Select all

minetest_findbiomes/init.lua:66: attempt to get length of global 'biome_ids' (a nil value)

Seems that bug was introduced when v6 support was added and variable scope was messed up.[/s]

Edit: It's been fixed in the latest commits.

Thanks!

Version 1.0.0 released!

Changelog:

• You can now find biomes not in the same height as you. Much more convenient that way!
• No longer teleport outside the map
• /findbiome now supports searching the special “default” biome (fallback biome in non-v6 mapgens), if it exists. There's no 100% chance it will find it (even if it exists in the world) and the algorithm isn't very smart, however. But it helps to see if your biomes still have large “holes”. The “default” biome is intentionally not listed in /listbiomes because it's just a fallback

[texmex]

Is this mod supposed to be only for direct player use or do you plan on adding API functions for other mods that may want to search for biomes (and return data only, not necessarily teleport the player).

[Wuzzy]

This mod is a fork from the mod “spawn” in Minetest Game. It finds a spawn position in an “easy” biome for new players. So if you need that, use that.

I do not plan to add an API.

Hi Wuzzy, nice and usefull mod. Thanks.
I'm using your mod to tune up biomes in a ocean-underwater game, and I'm getting problems in finding underwater biomes, such as corals. Is there anything can be adjusted in your code or does it depends on the minetest.get_biome_data(pos), that is not able to retrive underwater biomes (because they are not suitable for spawning)?.

[Wuzzy]

If I remember correctly, your current height at the time of using /findbiome matters. So try starting at ocean height to find ocean biomes.

[Hagrid669]

Starting at sea level or even under seems not working as well :( I solved for now stretching underwater coral biomes up to water level +1, this way /findbiome does its job right. It's a great help in developing, thanks again.

[Wuzzy]

This mod has been migrated to Codeberg.org: https://codeberg.org/Wuzzy/minetest_findbiome

Also, a tiny update 1.0.2 was released, just clarifying license stuff.

[Wuzzy]

Version 1.1.0 has been released!
This version is for developers, making the function "findbiome.find_biome" public. So biomes can be found by other mods as well.

Additionally, I updated the calculation of the map boundaries by using Minetest's builtin function instead, making it a little bit more accurate.

@Josselin2 - Edit the init.lua file and change line 128 from:

Code: Select all

res = DEFAULT_SEARCH_GRID_SIZE

to

Code: Select all

res = DEFAULT_SEARCH_GRID_RESOLUTION

[Wuzzy]

Sorry for the inconvenience. This bug is fixed now in the just-released version 1.1.1.

[SaKeL]

Nice mod Wuzzy! One suggestion I would have, the ocean/deep ocean biomes are still very hard to find. It does find some blobs of water underground somewhere but when I fly above the surface there are mostly no oceans at all. I think in this case the search would be more efficient from top to bottom (ymax to ymin) so it finds the oceans/deep oceans from the surface rather then underground cave what happen to be in the ocean biome.

[Wuzzy]

I've just released version 1.2.0. This update adds a new public function called "findbiome.list_biomes()" that allows you to get all biomes from Lua code.

Kindly contributed by Skivling.

@SaKeL: Yeah, this is tricky to figure out how to do it right, and tbh I don't really care enough right now to do it.

[SaKeL]

No worries its just a suggestion...still a good mod 😉
